JOHN B. DANJEAN, OF FOSTER, LOUISIANA.

PIPE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 453,105, dated November10, 1891.

Application filed April 4, 1891. Serial No. 387,649. (No model.)

To all whom it may concern:

Be it known that I, JOHN BERTRAND DAN- JEAN, a citizen of the UnitedStates, residing at Foster, in the parish of St. Marys and State ofLouisiana, have invented certain new and useful Improvements in aPipe-Cutter; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable Others skilledin the art to which it appertains to make and use the same.

My invention has relation to improvements in pipe-cutters, and thenovelty will be fully understoodfrom the following description andclaims when taken in connection with the accompanying drawings, in whichFigure l is a side elevation of my improved implement. Fig. 2 is alongitudinal central section of the same, the handle being in elevation.Fig. 3 is a perspective view of the sliding jam removed. Fig. 4 is atransverse section taken in the plane indicated by the line a; a: onFig. 2, and Fig. 5 is a perspective view of the cutting-die.

In the said drawings similar letters indicate corresponding partsthroughout the several views, referring to which A indicates the stockof my improved implement, which is provided with a suitable This stockA, which is formed integral, comprises the main body portion b, theforwardly extending short branch 0, and the forwardly-extendin g branchd, which is provided at its end with an angular portion 6, having anangular inner side designed and adapted to bind upon a pipe duringoperation.

B indicates the sliding and gripping jaw or block of my improved cutter,which is provided with the vertically and rearwardly extending sideflanges f, whereby it is guided within the branches 0 and d of the stockA. Taking through the center of the block B, which is provided with anangular bearingface g, is a forwardly and upwardly directed bore h,which is designed to sheathe the cutting-die presently to be explained.Taking transversely through theblock B, at a suitable elevation withrespect to the bore h therein, is a rod 2', which is recessed at itsmiddle within said bore h and is designed to form a stop to limit theinward or downward movement of the cutting-die.

The cutting-die O, which is approximately I of the proportional sizeillustrated, is of a general circular form in cross-section, but isprovided with a flat upper side for the greater portion of its length,whereby'a shoulderj is formed adjacent to its forward end, which bearingagainst the transverse rod t' limits the inward or downward movement ofthe die. Extending forwardly from the forward end of the die 0 is theintegral cutter 7a, which is preferably provided with an oblique edge,as illustrated.

As better illustrated in Fig. 3 of the drawings, I form a verticalchannel Z in the lower portion of the bearing-face of the block B and inalignment with the cutting-die, whereby the cuttings are conducted awayfrom the die and prevented from interfering therewith. Takingcentrally-through the body portion 1) of the stock A is a bore, asillustrated, which is screwthreaded for the upper or forward portion ofits length and is designed to receive an adjusting-sleeve D, which isscrew threaded for the greater portion of its length and is adapted tobear against and adjust the sliding jam or block B toward and from thebearing branch 6 of the stock, This sleeve D, which is provided with amilled head m,

is also provided with a screw-threaded bore and a slightly-enlarged boreadjacent its forward end.

E indicates the die-adjusting screw, which takes through the sleeve Dand is provided with a milled head '11, whereby it may be turned toadjust the die 0 with respect to the jamor block B. I

By the construction described it will be seen that the sliding jaw orblock may be readily adjusted by the threaded sleeve D, and

that the cutting-die may be readily adjusted independent of the sleeve Dby the screw E, whereby said die may be fixed to out various depths. Itwill further be seen that by removing the die 0 the cutter is readilyconverted into an efficient and strong pipe-Wrench,

Although I have minutely specified the construction and arrangement ofthe several elements of my improved implement, I do not desire to bestrictly confined to such construction, as it is obvious that suchchanges or modifications may be made as fully fall within the scope ofmy invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 15-

1. In a pipe-cutting implement, the combination, with the stockcomprising the body portion having a threaded bore, theforwardlyextending short branch 0, and the forwardlyextending branchhaving an angular portion at its forward end, of a sliding jaw or blockprovided with a bore, a rod taking transversely through the block so asto intersect the bore thereof and having a recess within the bore, acutting-die sheathed in the bore of the jaw or block and having a flatupper side and a shouldered end, a threaded screw taking through thethreaded bore of the stock and having a threaded bore, and another screwtaking through the bore of the firstnamed screw, substantially asspecified.

2. In an implement of the character described, the combination, with thestock having a threaded bore in its body portion, the sliding jaw orblock B, provided with a bore an d adapted to be moved in the stock, andthe adjustable cutting-die sheathed in the bore of the said sliding jaw,of an internally and externally threaded sleeve taking through thethreaded bore of the stock and adapted to bear against and adjust thesliding jaw, and a screw taking through the threadedbore ofthe-jaw-adjusting sleeve and adapted to bear against and adjust thecutting-die, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. DANJEAN.
